To ciliwhom it may concern:

Be it known that we, innisrorn Nrnrn and Ciiaisfroi Boon, hot-h citizens of the Empire of Germany, a .d residing at Nuremberg, in the Emoiz'e of Germany, have invented a new and useful Receiving Electric System, of which the following is c. specification.

Our invention reiates to a receiving electric sysi-crn Wi ch is adasotod to be controlled over distanc and comprises a receiving circuit, a dis'ariouter, u primary circuit con- *troiied by, the receiving circuit for operating the distributor, a series of electromotors, a series of secondary circuits con troiled by the distributor and including the electroinotors, a series of cut-outs adapted to control various electric operating circuits, and a series of intermediate gears connected with the eiectroc motors and ada )ted to open and to close the cut-outs. The electric operating circuits may include various known devices, machines, apparatus, or the like which can he set to Work and he stopped by the cut-outs. The receiving electric system may he disposed at some ilace and may be controlled over distanre means of a single conductor iine or by means of electrical Waves. The receiving: electric system may also be disposed on board a ship, or on an aerostutic vessel or -machine, or in a torpedo, or on any other un manned vessel or vehicle, and can he controlled over distance means of electrical Waves. in any casei is rendered possible to select any of the devices, machines, apparatus, or the like under the control of the receivinc electric system and to set it to won: and to stop it as may be required. the devices, machines, apparatus, or the like may he disposed in groupsfwhich are controlled from the cut-outs, so that if any group is selected, the several devices, machines, apparatus, or the like comprised in this group stopped.

tric system adapted to be controlled over distancehy means of electrical Waves.

Figure l is a diagram of the receiving elec tric system, Fig. 2 is an elevation of a distributor on the left and relay on the right included in the receiving circuit and adapted to operate the distributor, the binding posts of the relay being put on the other side for The receiving electric sysr'gem illustrated at.

-1 comprises an aerial conductor 42 or its equivalent, a coherer 38, a receiving circuit 43, 37 with a source of current -14: and a relay R (consisting of electromagnet 39 and armature 36), a primary circui 45 operated by the relay and including a source of current 13 and a relay R, a distributor D operated by the relay R, a series of clectromotors E, E E, E, E, E, secondary circuits 15, 76, 1.), 5% connecting the several electromotors E, E with the distributor l) and a source of current i, a series of intermediate gears l, and a series of cutmuts C controlllcd thereby and inserted in operating circuits 77, 78. The tapping device 40 for the coherer 88 is shunted to the source of current 13 by lines 46 and 47.

The relay l1 (Figs. 2 and I3) is shown as consisting of air of electromagnets 14 disposed on some oase piate of insulating mate rial, of which only the top surface is indicateo by line 50 in Fig. 2. Ql'ose by the elec roinagnets 14: is an angular hracliet 51 oi any Known construction, in which a shaft 52 is fastened. A two-armed lever S, 9 is mounted on this sha 52 :0 rock and is conneoccd with a hclica ng 1i surrounding the shaft which sprino 11 tends to press the longer'arrn 8 down rd. This doWnward motion is normally checked by a s'to- 53 forming a part of the bracket 51. The short arm 9 is rigidly connected with an armature 12 common to the two electromagnets i4, 14. E e two binding posts 48, 19 with Whicl the coil of the electromagnets Li,

' (Fig. 4) of the distributor D.

studs 59 an end carries a pawl 14 is connected,-are indicated by the same characters of reference in Fig. 1. The upward turn of the long arm 8 under the action of the electromagnets 14 is limited by a snitable stop 54 provided on the frame part 55 The free end of the arm 8 carries a spring-pressed pawl 10.

The distributor D (see Figs. 2 and 3) co1nprises the justmentioned frame )art and a stationary disk 2, in both of which a shaft 55 is mounted to turn. This shaft 56 has fastened on it a crank 5 and a ratchet wheel 7, in which latter the spring-pressed pawl 10 engagesi A contact spring 57 (Fig. 4-) is made to bear against the nave 6 of the ratchet Wheel 7 and is electrically connected by a line 58 with one pole of the source of current 4 mentioned above (Fig. 1). The stationary disk 2 is shown as provided with six studs-59,

- 59 for carrying six contact springs 3, 3, which in lfig. 13ers shown as forming the free ends of helical s rings 60, 60 surrounding the (i normally bearing against stops 6d, 61. The contact springs 3, 3 are electrically connected with the lines l5, 15 shown at 1 and are in any known manner insulated irom the shaft 56 and from one another. The crank 5 is adapted on being rotated to strike the several contact springs 3, 3 one after the other for closing the respective secondary circuit 15, 76, 19, 4,

The six electromotors E, "E E in Fig. 1 maybe of any known construction. In Figs. 5 and 5 each of them is shown to be a series motor consisting of a pair of electrome ncts 17, 11 two common polar pieces 62, 62, caring arms 63, 63, an armature 6 and a commutator with two contact brushes 68', 66. The armature shaft 67 fastened on its outer end a pulley ti, on which one end of a rope 20 or the like is secured for conncct-' ing the electromotor E with an intermediate ear I, Winch-is constructed as follows. A ever 22 is mounted to rock on a pin 68 fastoned in two suitable supports 69 and 70 and its free end is connected with the other end of the rope 20 or the like, a helical spring 21 bein preferably inserted between thorn.v A

be ical spring 23 surrounding the pin 68 and having its one end fastened on the su port 70 tends to ress with its other end the ever 22 u ward and thus to return the arninture s aft 67 into its initial position. Between the electromotor and the shaft 68 a bracket 7.1 is disposed, which carries a pin 2., On this pin 29 a ratchet wl'leel 28 mounted to turn, which by its nave is rigidly co 1 ed with a star Wheel 30. Another level 4' mounted to rock on a in 72 lastened iii iv; supports 73 and Y4 and is pressed upward by a helical spring 24 surrounding; the pin 72 in a similar manner as the lever 22. A stop 26 on the bracket 7.1 serves for limiting the upward turn of the lever 25, which latter at its free 71 serves for limiting the downward turn of the lover Close by the star wheel 30 is disposed a cutout C consisting of two contactsprings 31 and 32. The contact spring 32 -.carrics a rounded-oil or semicircular tooth 33 which is adapted to engage in the spaces of the star Wheel 30. T he pitch oi the teeth oi'the star Wheel is double that ol' the ratchet Wheel, so that when the tooth 33 on the contact spring engages in the respective space of the star Wheel the free end of the contact spring 32 will be detached from that of the other contact s ring 81, so that the cut-out C is opcne( but when the ratchet wheel 28 is fed one tooth forward, the next tooth of the star Wheel 30 will push oil the contact spring 32 against that of the other contact spring 81 for closing the contact C, which is inserted in a corresponding operating circuit 77,. 78. This circuit includes one or, more electric de vices, machines, apparatus, or the like of an y known kind which it is desired to set to wbrk and to stop. A. regulating screw'75 in a pro jection' of the bracket 71 serves for adjusting the contact spring 31 so as to insure its proper contact with the spring 32. The lever 25 carries a bent leaf spring 34, which the lever 22 can eventually strike and depress.

Each electroinotor E shown to be rovided with two binding posts '16 and 18 (Fig. 6), of which one 16 is connected by the corresponding line 15 with one contact spring 3 of the distributor D and the other binding post 18 is connected by a line 76 return 19 that in turn is connected with the other pole of the source of current 4.

It will be seen, that for the position of the v cranlo5 oi the distributor D shown at Fig. 1,

in which it is in contact with one contact spring 3, the elcctromotor E will be inserted in the circuit of the source of current 4.

The receiving electric system described operates as follows: When it is desired at the sending station in selecting the electro- 17001501 E to set it to work, the respective key .15 operated. for sending electrical Waves through the space to the aerial conductor 42 or its equivalent of the receiving electric teln. Each time when an impulse circulates through the receiving circuit 38, 43, ll, 44, 3'7, tle relay R will be inonn-uiturily onergizel'i for attracting its armature 36 and thereby momentarily closing the primary circuit 13, 35, 45, so that'thc relay it is momentarily energized and at the same time the tapping device 40 is operated for returniz the cohcrer 38 to its initial state. The ener ized relay R will in attracting its armature 12 turn the two-armed lever 9, S, which on bcrng released feeds by its pawl 10 the ratchet wheel 7 one tooth forward- As that engages the ratchet many consecstive electrical waves must I with a main 50 stopped.

55 to its initial position, in which i! er 60 his key so many times us to cause the crun strikes the first contact sprint: 3 (as shown ill Fig. 1) the first electromotorli ill he thereby caused to turn and to wind the rope on its pulley 41, whereby the lever 22 of the in- .pt'ermediutc gear I will he gradually turned lSi'loWn'Wurd, 'so that it will approach the bent spring 34: (Fig. 5). Ii, however, impulses continue to consecutively circulate in the receiving circuit 38, 43, it, 44, 3'7 and cons'cquentlv also in the primary circuit 13, R,

20 35, 45, the crank 5 will soon leave. the "first Contact spring 3 before the lever 2;? has come in contact nith the bent spring 34, so that the clectrolnotor E .will become without current, when the spring-pressed lever illreturn by the rope 20 the armature shaft 67 to its initial position. Then the crank 5 will alterwardstrike the second spring 3 and thereby close thecircuit 1.5, 76, i9, 4 ol the second elcctromotor E which will start hut '30 soon stop, as the crztnn again leaves the second contact spring 3. ()nly when the .crahh 5 strikes the third cont-octspringB and stops (no more electrical waves being sent over from the sending station), the third '35 electromotor E will run for e, sufficiently long time to enable its lever 21? to strike und depress the bent spring 34 and thereby also the lever 25, so that its pawl 27 leeds the ratchet wheel 28 one tooth tomverd and the star wheel 30 pushes oil the contact spring 32, sons to close by the cut-out the corresponding operating circuit 77, 7'8 for setting the therein included devices, machines, ILPPKtrzitus, or the like to work. The lever 25 being checked hv the lower stop 79, the

electrcunotor will hy the rope 2i: dram out the helical spring 21 and so produce such s strong tension, that the urnnitiu-e 64- is prevented l'roin l'urthcr running and is lorcili ly At the scndizw stution the operattor will know from his experience or feeling the moment, zit which he must again depress his key repeatedly for cnusi the crank 5 to :5 or to return leave the third contact sp the space hctwccntu o contact sprin i T'a hen the operator nuts to again st y; the device, i'nuchinc, apparatus, or the like hud stair-ted. of course he will have to depre- 5 to strike and depress the third contact s I i s ring 3 for u ufhcientivlong tune to cnzthlc t .e third clcclroinotor to uctunte its in-- terniedizitc gear l for feeding the ratchet wheel 28 one tooth forward and thus opening by the cut-out C the operating circuit 77, 78.

From the shore explanations it will be olorious in WAS-t manner any of the electro motors E, E E, can he selected and set to worlc for closing or opening 037 its intermediate gear and cut-out the correspondhrc operating circuit 77, '28 and that several of these eieclrornotors can he set to work one after the other and in any determined order for producing the desired effects.

The receiving electric system can be varied in many respects without departing from the spirit of our i ntion. When a single conductor line is to connect the sending station with the receiving station, of course, the coherer 38 with its topping device 40 is dispensed with, While the son cc of current may he einpl yed or omitted (in case one is zit the sending tution) and the line 37 may be connected Wit/l1 o ground-plate.

it will have to depend upon the circunn stances, whether the crcrul open ting: circuits 7T, 78 are to receive each a separate source of current or fill of them a common source of current, or whether the are to be supplied with current from the source of cur rent kin any known manner. lt is ohrious, that the operating circuits 77, 2'8 can be connected with ordinary or subnmrine mines.
